Programma dettagliato e risultati di apprendimento attesi

The course is an introduction to the physics of soft materials, complex fluids, and biological systems, ranging from simple colloidal suspensions to polymer and polyelectrolytes, spontaneous surfactant aggregates, gels, proteins, nucleic acids, “active” matter. Besides providing a bottom-up presentation of the properties of complex fluids, based on their microscopic structure and interactions, the course aims at highlighting the important practical applications of these materials in the general market and for nanotechnologies. A survey of the experimental techniques of major interests for the investigation of soft material is given, with lab demonstrations, in the last part of the course.

Descrizione degli argomenti trattati

Arg.1. Review of statistical thermodynamics. Microscopic meaning of the entropy. Canonical distribution and Maxwell-Boltzmann statistics. Gran-canonical distribution for open systems. Statistical mechanics of suspensions.

Arg.2. General introduction to disperse systems and supramolecular systems. Dilute suspensions and osmotic pressure. Effective forces between dispersed particles: excluded volume, van der Waals and electrostatic interactions, depletion forces. Brownian motion

Arg.3. Colloidal dispersions. Stability of a suspension of colloidal particles and colloidal aggregation. Colloidal crystals, glasses and hydro/aerogels: applications in chemistry, nanotechnology and photonics. Colloidal aspects related to pollution, water treatment, and oil recovery. Aerosols and their relation to environmental problems

Arg.4. Polymer solutions. Dilute solutions and polymer coils. Semidilute solutions, polymer meshes, and Flory-Huggins theory. Physics of plasticity and rubber elasticity. Viscoelastic properties of non-Newtonian fluids and reptation model for elastomers. Polymer gels.

Arg.5. Active colloids: kinds of active colloids available, “phase diagrams”, types of motion and collective dynamics;

Arg.6. Polyelectrolytes: intra-chain electrostatic interactions; Manning condensation; counterion condensations; polyelectrolyte gels.

Arg.7. Surfactant solutions. Classes of surfactant and their practical applications. Micellization and basic principles of detergency. Self-assembly of surfactant molecules: micelles, “living polymers”, inverted micelles, and vesicles. Emulsions and their stability. Micro and nano-emulsions, and their impact in food preparation, drug delivery, and enhanced oil recovery. Pickering emulsions.

Arg.8. Biological fluids. Protein structure. Enzymes and biocatalysis. Transport , structural, and membrane proteins. Protein crystallization. Structure of the nucleic acids and DNA replication. Molecular machines.

Arg.9: Experimental methods to investigate soft and biological materials. Light Scattering, correlation spectroscopy, video microscopy, and microfluidics techniques (with lab presentations).              

All these  arguments   are treated in the  lectures notes by R. Piazza accessible on the Beep platform to the students participating to the course, wherefrom  several good review papers on soft and biological matter can also  be freely downloaded.


Note Sulla Modalità di valutazione

The course is organized as a series standard classroom lectures, in which the main theoretical arguments are developed, supported by the discussion of specific applications, to be regarded as exercitations. The final test consists of an oral exam.

Note:

This is not a textbook, but rather a popoular science book written in a plain language and accessible to a large audience. Yet, it contains most of the physics we need

Risorsa bibliografica facoltativaR. A. L. Jones, Soft Condensed Matter, Editore: Oxford University Press, Anno edizione: 2002, ISBN: 978-0198505891
Note:

A slim and accessible introduction, although at a level which is not as advanced as the one of this course

Risorsa bibliografica facoltativaT. A. Witten, Structured Fluids, Editore: Oxford University Press, Anno edizione: 2010, ISBN: 978-0199583829
Note:

A very good book, at a level a bit more advanced than the one of this course, and with a more theoretical lingo

Note:

Probably the best introduction to biophysics
